Biology Activities

How can a mixture of molecules be separated from one another? Laboratories rely on gel electrophoresis to separate a wide variety of samples, from DNA used in forensics and for mapping genes, to proteins useful in determining evolutionary relationships.
Humans are born with five basic senses—hearing, sight, smell, taste and touch. Perform tests to determine the acuity of each of these senses.
Infections and parasitic diseases may be spread from person to person through air, water, and physical contact. Show students how easily germs can spread and emphasize the importance of good hygiene using fluorescent lotion.
The process of DNA extraction is of primary importance in many fields of biotechnology. It is critical for genetic research, DNA fingerprinting, and creating recombinant organisms to produce beneficial products in the field of medicine.
Stare at an object straight ahead. Can you see anything else out of the “corner of your eye”? Seeing beyond the center of our visual field is known as peripheral vision. Explore the range of your own peripheral vision.
Cell membranes help hold cell contents within the confines of the cell. If a cell membrane is damaged physically or chemically, the contents of the cell can “leak” out. In this activity, students can observe the red pigment (betacyanin) after it has left beet cells that have been damaged to varying degrees.
Demonstrate yeast respiration—and simulate the effects of chemical pollution.
Five major water quality factors: Basic tests at minimal expense for students at all levels.
Easy, economical way to discover what the first visible traits of tiny sprouts reveal
How to maximize the performance and lifespan of your dissection instruments.
This is a great demonstration to teach concepts of acids and bases, solubility, digestion, and “antacid-testing” consumer biochemistry.
Inexpensive experiment helps students explore the variables affecting protein digestion.
Simulation of predator and prey interaction
